5 Claims.

The present invention pertains to ejectedbobbin receivers for bobbin changing looms, and more particularly relates to such receivers of the type comprising a receptacle having a bobbin receiving apron therein.

Ejected-bobbin receivers of the type to which my invention applies commonly include a suitable receptacle, such as a can, which is positioned beneath the battery of a bobbin changing loom for receiving the empty bobbins which are ejected from the loom shuttle. It has been proposed to provide such receptacle with a fabric-covered bobbin receiving apron secured to the receptacle in position to receive the impact of the ejected bobbins, to thereby cushion the fall of the bobbins and prevent the bobbins from becoming splintered or broken. Such bobbin receiving aprons are particularlydesirable when weaving with rayon filling.

A principal object of the present invention is to provide an ejected-bobbin receiver comprising a receptacle and apron as aforesaid, and novel and improved means for detachably securing such apron to the receptacle, which means shall preferably be so constructed as to be capable of securing the apron to exsiting bobbin cans without alteration of the latter, and to allow the apron to swing out of the way when the receptacle is to be emptied.

The foregoing and other objects of the invention are accomplished in the construction illustrated on the accompanying drawing, of which:

Fig. 1 is a view in perspective showing part of a bobbin changing loom having a receptacle equipped with my improved bobbin receiving apron;

Fig. 2 is a View in elevation of said receptacle and apron;

Fig. 3 is a side view of the same; and

Fig. 4 is a view of said apron detached from the receptacle.

The loom shown on the drawing is generally of usual construction not of the present invention, and is accordingly but fragmentarily illustrated. The parts shown include a right hand loom side l, the lay 2 having a shuttle box 3 and ejected-bobbin chute or guide 4 thereon, a shuttle 5 having filling supply 6 therein, a picker stick 1, and bobbin changing mechanism including a transferrer 8. The filling supply is carried on bobbins 9 and when the supply on a bobbin is exhausted the bobbin is ejected from the shuttle down the guide 4 as is well known in the art.

A receptacle for receiving the ejected bobbins 9 is placed beside the loom side I underneath the Hopedale, Mass, a cor- 1939, Serial No. 268,098

guide 4. In the particular embodiment shown 0 this receptacle consists of a conventional form of bobbin can It having the preferred form of my improved bobbin receiving apron H therein.

The can It] is formed from metal and has an open top for receiving the bobbins 9. The bobbins are ejected, and enter the can, with sufficient force that they would be battered or splintered if allowed to strike either the can or other bobbins in the can. The apron II is provided to cushion the fall of the bobbins and thus prevent said damage.

The particular can ill has a bottom l2, front and rear walls l3 and M, respectively, and sides l5. wardly above the top of the can and is curved rearwardly and downwardly to form a handle l6. As thus constructed, the upwardly extending part of the front wall l3 has side edges H.

The apron ll consists of a frame l8, a fabric cover l9 therefor, attaching hooks 2t, and a spring 2i. The frame 18 consists of a length of resilient wire or rod bent to form three sides of a rectangle and having its ends bent to form loops or hooks 22. The frame is sufficiently rigid to keep its shape as shown but sufficiently resilient to yield when the apron is struck by an ejected bobbin. The cover I9 is formed from canvas or other fabric and consists of an envelope which is slipped over the frame [8 and fastened in any suitable manner.

The hooks 20 serve to attach the upper edge of the apron to spaced edges such as edges I! at the top of the front part of the can, with the apron extending from its upper edge downwardly and rearwardly within the can. The particular hooks 28 shown each consists of a wire or rod bent into U form, the hooks being connected together by the coiled spring 2|. The hooks 20 are received in the hooks or loops 22 so as to be pivoted for movement about a horizontal axis which is located at the upper edge of the apron.

The apron ll having hooks 20 pivoted as described may be very quickly and easily attached to existing bobbin cans such as the can l0. Before the apron is so attached, the hooks 20 will be turned so as to project from the rear or concave face of the apron. Then the apron is placed in position in the can with the upper edge of the apron and the pivotal axis of the hooks substantially coinciding with the axis of the handle l6. Then the hooks are rotated along the edges I! to the position shown, and the apron is thereby attached to the can. The spring 2| yieldingly urges the hooks 20 together, and thereby holds The top of the front wall 13 is extended upthe hooks in firm engagement with the side edges H. The apron may be quickly detached from the can by a reversal of the operation just described.

The apron II is attached to the can II] only by the hooks at its upper edge and is otherwise free and unsupported. The apron extends from its upper edge downwardly and readwardly within the can, in position to be struck by the ejected bobbins 9. Being resilient, the apron will yield to cushion the fall of the ejected bobbins and thereby prevent the bobbins from being damaged. The construction is such that the apron is, in effect, pivoted to the hooks 20 and spring 2| for movement about its upper edge. Thus, when the bobbin can is inverted to empty it of bobbins, the apron l I will swing out of the can. It is accordingly not necessary to remove the apron when the can is to be emptied, and the apron will in no way interfere with the emptying operation.

Having fully disclosed the preferred embodiment of my invention, I claim:

1. An ejected-bobbin receiver for bobbin changing looms, comprising a receptacle having an open top and spaced edge portions formed adjacent said top at the front thereof, a fabric-covered bobbin receiving apron, and means for detachably securing said apron at its upper edge to said edge portions with the apron extending downwardly and rearwardly within said receptacle, said securing means comprising a pair of hooks located respectively at opposite corners of said upper edge of said apron, said hooks being pivoted to said apron for movement about an axis parallel to said upper edge in moving into and out of engagement with said edge portions.

2. An ejected-bobbin receiver for bobbin changing looms, comprising a receptacle having an open top and spaced edge portions formed adjacent said top at the front thereof, a fabric-covered bobbin receiving apron, a pair of hooks for detachably securing said apron at its upper edge to said edge portions with the apron extending downwardly and rearwardly within said receptacle, said hooks being pivoted to the opposite corners of said upper edge of said apron, and

spring means for yieldingly holding said hooks in firm engagement with said edge portions.

3. An ejected-bobbin receiver for bobbin changing looms, comprising a receptacle having an open top and a front wall extended upwardly above said top to form a handle, a resilient fabric-covered bobbin receiving apron, a pair of hooks for detachably securing the upper part of said apron to the respective side edges of said handle, said hooks being located at opposite sides of said apron, and spring means for yieldingly holding said hooks in firm engagement with said edges, said hooks comprising the sole means attaching said apron to said receptacle whereby the apron may yield when struck by an ejected bobbin.

4. An ejected-bobbin receiver for bobbin changing looms, comprising a receptacle having an open top and a front wall extended upwardly and curved rearwardly and downwardly to form a semi cylindrical handle, a fabric-covered bobbin receiving apron, and a pair of hooks located respectively at opposite sides of said'apron for detachably securing the apron to the respective side edges of said handle, said apron being pivoted to said hooks for movement about its upper edge whereby said apron may swing out of said receptacle when the latter is to be emptied.

5. An ejected-bobbin receiver for bobbin changing looms, comprising a receptacle having an open top and a front wall extended upwardly and curved rearwardly and downwardly to form a handle, a bobbin receiving apron comprising a frame covered with fabric, a pair of books pivoted to the upper edge of said apron for detachably securing said apron to the respective side edges of said handle, said hooks being movable about an axis parallel to said upper edge in moving into and out of engagement with said side edges of said handle, and a tension spring connecting said hooks and yieldingly holding the hooks in firm engagement with said side edges, said hooks comprising the sole means attaching said apron to said receptacle and said apron being movable about said axis whereby the apron may swing out of said receptacle when the latter is to be emptied.
